Application filed July 7,

v This' inveiltion relates to an improved pad to be used for polishingand cleaning varnished 'surfaces'and metal surfaces and for producing aglossy finish thereon, and further 6 relates to the method of making thepad.

It is well known that in compounds and liquid preparations heretoforeused in clean ing and polishing metal surfaces, the fact that theycontain benzine or gasoline, renders them 10 dangerous andobjectionablein use. Some ofthem, while serving to clean the metal surfaces, leavethe same liable to corrosion, and do not produce a polish thereon.

The\clevice hereinafter desribed is convenient, and particularly rapidin its action, and is particularly free from corrosive effect.

The drawing illustrates a form of this invention which I have found tobe desirable in use.

In the drawing, the figure is a'perspective view of a polishing padconstructed in accordance with my invention.

The device consists of a substantially rectangular pad 2, having holes 3extending laterally therethrough. i

In the fabrication of this polishing pad, I first take a quantity ofhorn material, preferably deer horns, and bake them with a heat,

and then powder them. Tothis horn material, I add powdered squid shell(designated by some as cuttle-bone) and to these ingredients I addpowdered pumice stone; the proportions being: powdered horn, one part;powdered squid shell, two parts; and powing these ingredients, I adda'quantity of gelatin, and again mix the same thoroughly into a paste. Ithen take a quantity of animal hair and cut the. same into suitablelengths, and mix it with the gelatin paste. I

- then compress the same, and, after suitable drying, I cut the hairfelt compound into suitable pads.

In use, the pad is dipped into .water, and,

.- after the surplus water is squeezed out, the

ad isr'eady for use in polishing a metal surr ace, and also enameledwood and varnished surfaces.

The compound or mixture of the present invention possesses the ualitiesof effecting a uniform and -perfect c caning and brightendered pumicestone, seven parts. After mix- 1927. seriino 204,125; I w

ing of metal surfaces when applied thereto and subjected to thenecessary rubbing; producing a lustrous and gloss finish.

en used as specified, 1e water serves as a vehicle for the otheringredients, and the gelatine and powdered pumice stone remove dirtwithout scratching or marring, although the pumice has abrasiveproperties. i The powdered horn and powdered squid shell produce aglossyand brilliant polish. The hair ingredient serves to retain the otheringredients ina relative mass orform, and the homogeneous pad thusformed efliciently cleans and polishes, and gives a more lustrous.finish, than can be obtained with ordinary cleaners, and the rubbingafterward-with cloth or chamois skin.

The olishing pad thus fabricated, contains no aci s, benzine, naptha, oralkaline ingredients, andwill not injure the hands of the user. Inaddition, the gelatine and other smoothing ingredients such as thepowdered squid shell, deposit on the polished surface, an exceedinglythin film'or co'at whish pre- 7! serves the metal from corrosion. Nolimitation is made to the form of the pad shown in the drawing, as thesame may be made any size or form desired without departing from thespirit of the invention. 80

What is claimed is:

l. A polishing pad, consisting of a body of hairfelt having holesextending laterally therethrough, and polishing ingredientsiiolmogeneously compounded with the hair e t. 2. A polishing pad,including-a body}. of hair felt, anda compound incorporated therein,consisting of powdered horn; one part, powdered squidshell, two parts,powdered 00 pumice stone, seven part-s, -and gelatin.

3. The herein desrribed composition of matter fabricated into apolishing pad,-.con-. sisting of animal haircut into short lengths,gelatin, powdered horn, powdered squid shell,

and powdered pumice. stone, combined, substantially in the manner and inthe proportions stated.
